PUF ZP Z-shaped elements
PUF ZP Z-shaped elements are elements of a curved shape assembled at the factory from pipes and bends in polyurethane foam insulation.
To ensure the long service life of the PUF layer, zinc-plated coating is used.
Identification code review
Russian abbr.: Z – образный элемент, Ст 09Г2С (ГОСТ 8732-78) 219x6,0 – 1 - ППУ - ОЦ
English abbr.: Z-shaped element, St 09G2S (GOST 8732-78) 219x6,0 – 1 - PUF - ZP
Below is the explanation of the marking conventions:
2. «GOST 8732-78» denotes steel seamless hot-worked pipe;
3. «219» is the pipe diameter;
4. «6,0» is the pipe wall thickness;
5. «1» is the insulation type;
6. «PUF – ZP» is the polyurethane foam insulation, zinc plated protective shell.
